ADDING AND WRITING MACHINE.

Specification of Letters Patent.

Patented Feb. 18, 1913.

To all whom it may concern:

Be it known that we, SAMUEL G. DORMAN and WILLIAM H. CLAYTON, citizensof the United States, residing at Poplar Bluff, Butler county, Missouri,have invented a new and useful Adding and Writing Machine, of which thefollowing is a specification.

This invention relates to adding and. recording machines of the typewherein two recording mechanisms are employed to record upon one platen,one of said recording mechanisms serving for the adding mechanism andone acting for usual typewriting purposes.

An object of the invention is to-produce a machine of the characterreferred to consisting of two independently operable recordingmechanisms, one of whichcoiiperates with the'adding mechanism, andone ofwhich is operable to produce typewritten records, and both operating torecord upon paper on a single platen, and provided with means under thecontrol of the operator whereby the records produced by one of saidmechanisms may be in one color, and the records produced by the othermechanism may be in a distinctive color..

Another object of the invention is to produce a combined adding andtypewriting machine in which any portions of the rec ords may beproduced in one color, and any other desired portions of the records maybe produced in a distinctive color; such, for instance, as thetypewriting records to be of a single color throughout, and the addingmechanism records of a single color throughout which is distinctive fromthe typewriting records, or port-ions of either or both records may berecorded in distinctive colors.

i The particular features of the typewriting mechanism detached from theadding mechanism are shown and described in the application of WilliamH. Clayton for a typewriting machine, filed September 10, 1906, SerialNumber 334,029; and the par:

ticular features of the adding mechanism detached from the typewritingmechanism aresh'own and described in the application of Samuel G.Dorman, for an adding and recording machine, filed October 16, 1906,Serial Number 339,230.

The invention also relates to specific improvements upon that type ofadding and writing machines which is the subject-matter of the patent toHubert Hopkins dated September 24, 1912 and numbered 1,039,130, and thespecific object of the invention is to combine the typewriting andadding mechanlsrns thereof with a single polychrome ribbon to be actedupon by the type of both mechamsms and connections operated incidentallyto the operation of the typewriting mechanism and the recordingmechanism of the adding department of the machine to utilize one colorof the ribbon, and means for controlling the ribbon to utilize anothercolor of the ribbon in producing the records so that selected portionsof the records may be produced in distinctive colors upon the same sheetof paper without removing the paper from the platen.

With these objects in view we have illustrated one embodiment of ourinvention in the accompanying drawings in which Figure 1 is a sideelevation of a machine containing our present invention. Fig. 2 is aside elevation partially in section illustrating the train ofconnections from the typewriter keys to the typewriter type-bars. Fig. 3is a plan view of the machine with the case removed. Fig. 4 is alongitudinal sectional 'view of the machine illustrating the ribboncontrolling device. Fig. 5 is a sectional view along a line such as 55of Fig. 3. Fig. 6 is a detail view of a part of the recording mechanismincluded within the adding department of the machine. Fig. 7 is aperspective view of the ribbon shifting devices by means of which theribbon is moved to present the difi'erent desired colors thereof to beacted upon by the type of the two-recording mechanisms. Fig. 8 is asectional view illustrating the paper carriage and the support therefor,and also illustrating the ribbon moving device and the mechanism forcontrolling lateral movement of the carriage.

The subject-matter of this invention comprises the novel arrangement andcooperation of the two recording mechanisms whereby they may be operatedto record in different colors. The typewriter keys 1 are arranged intransverse rows upon a keyboard. The keys are mounted upon bellcranklevers 2 which are arranged in two groups. The upper or inner ends "ofthe typewriter key levers areconnected by links I The adding mechanismincludes a series 3 with levers 4 which, in the arrangement shown, arepivotally supported near the rear of the machine. The links 3 connectthe upper ends of the key levers with the lower endsof the levers 4 sothat when the typewriter keys are depressed the upper ends of the levers4 will be actuated rearwardly. Springs 5 connect the levers 4 with rods6 thereby actuating the upper ends of said levers 4 forwardly andholding the keys in their normal elevated positions. The typewritingtype bars 7 are ivoted upon spindles 8 which are mounte in pivotedframes 9. Actuation of the type bars 7 is effected by means of links 10which connect the type bars with the upper ends of the levers 4,respectively. Therefore, each train of recording devices in thetypewritlng mechanism includes a key 1 mounted upon the front end of thebell crank lever 2, the upper end of. which is connected to the lowerend of a corresponding lever 4 and a link 10 connecting each of thelevers 4 with a corresponding pivoted type bar 7 and a spring 5 actingto restore the keys and the type bars and the remaining members of eachtrain of connections to idle position after operation.

The platen 11 is mounted in a laterally movable carriage 12 and isoperable to hold and present paper to be acted upon by the type bars.Lateral movement of the paper carriage and platen is effected by asuitable escapement mechanism. One form of such escapement mechanism isillustrated generally in Fig. 8 and includes a rod or shaft 13 suitablysupported in bearings and having a pinion 14 meshing with a rack 15 onthe paper carriage. Step by step movement is effected throu h theoscillation of an escapement mem er 16 engaging with an escapementpinion 17 on the end of the rod or shaft 13. The oscillation of theescapement member 16 is effected on depression of the typewriter keys 1by the levers 4 engaging against a roll 18. The rod 18 is supported bydepending arms 19 rigid with the rock shaft 20 upon which the escapementmember 16 is secured. A motor 21 of any suitable construction andarrangement is supported by the frame of the machine and actuates ormoves the paper carriage laterally when such movement is permitted bythe operation of escapement devices in the well understood manner. Thespecific construction and arrangement of these devices are described indetail in the Clayton application #334,029 and do not constitute anypart of the present invention, and, therefore, do not require specificdetailed illustration and description particularly since any of theknown escapements and motor devices for paper carriages may readily beadapted for use in this machine.

of ten numeral keys 22 arranged in rows in the same key-board with thetypewriter keys, and, in the one embodiment s own, the adding, mechanismkeys are rearward from the typewriter keys. The keys 22 are mounted uponlevers 23 which are operable effectively to set up numbers in alaterally movable carriage 24. The numeral keys and key levers areoperable to setup numbers in the carriage 24 in the well understoodmanner as described in the Hopkins Patent, #1,039,130. The type-carriers25 are pivotally supported upon a shaft 26, and the racks 27 are alsopivoted upon said shaft 26 and control the movement of the typecarriers. A rock shaft 28 has a link 29 connected thereto and alsoconnected to the arms 30 which also swing from the shaft 26. Strongsprings 31 hold the shaft 28 in its idle position and return said shaftto idle position after each movement thereof. The arms 30 support a rod32 in front of the vertical arms of the racks and type-carriers, so thatwhen the shaft 28 is returned to idle position by the springs 31 theracks and type-carriers are also returned to idle position by the rod32. The arms 30 carry a rod 33 (Fig. 3), and said rod 33 is connectedwith extensions 34 of the type-carriers by springs 35, so that when thearms 30 are operated by forward rocking of the shaft 28, the rod 33 ismoved downwardly, thereby extending the springs 35 and moving thetype-carriers 25 in front of the laten, for ward movement thereof beinglimited by the carriage 24, in the well understood manned described inthe Hopkins patent. At the proper time, after the type-carriers arestopped in position to aline the desired type adjacent to the platen,type driving hammers 37 are automatically driven agalnst the type,thereby driving the type against the ribbon to make impressions upon thepaper carried by the platen. The shaft 28 is rocked by means of a handleor lever 38 (Figs. 1 and 3), and on completion of the printing by actionof the hammers against the type as above explained, the handle isreleased and the type-carriers and racks are returned to idle positionby the sprin 31. The automatic adding mechanism 0 the machine of theHopkins patent which is also embodied in this machine, includes a seriesof adding wheels 39 supported upon a shaft 40 mounted in a swingingframe 41, and automatically lowered out of mesh with the racks 27 justbefore said racks start forwardly in a recording operation, and areautomatically raised into mesh with said racks just before said racksare started on their return movement, thereby adding the numbersrecorded, in the well understood manner and operation of the Hopkinspatent aforesaid.

The mechanism for recording a total reprnented in theaddig mechanismincludes a key 42 arranged j and connected to the front end of a lever.48. When the key 42 is depressed it raises the rear end ofthe lever 43which is pivoted to another lever 44 sililplported upon a stud. Thelever 44 has a l' 45 connecting the rear end of said lever 44 with theoperating arm 46 whereby the swinging frame 41 is rated to raise andlower the adding wdmzel's into and out of mesh with the racks 27. vInthe well understood manner the operation of the link 45 by the key 42and t 0 connections therefrom to the operating arm 46 causes the addingwheels 39 to remain in mesh with the racks 27 during forward movement ofthe said racks, so, that any total or number re resented in the addingwheels will be printed. The lever 44 has an upwardly extending arm whichis connected to a link 47 extending toward the rear of the machine andconnected to an arm 48 on a rock shaft49. The rock shaft 49 is providedwith two arms 50 which car a rod 51. Depression of the key 42. througthe train of connections described, swings the rod 51 forwardly,actuating the sliding element 52 and lowering the abutment 53 in thewell understood manner to permit the racks and type carriers to moveforwardly to record the total represented in the ad ing wheels. The secific construction and arrangement of t e adding mechanism abovedescribed are well known, and it is in connection with these well knownfeatures of the adding mechanism and of the typewriting mechanism thatour present invention is em loyed and arranged to cooperate.

ur invention includes mechanism for movin f-" e ribbon to resentdifferent colors at the writing line ad acent to the platen so that thejoint records may be made in distin ishing colors for purposes ofdiflerentiation or other purposes. f

We will now describe the mechanism for moving the ribbon to present thedifferent colors thereof so that records in diflerent colors may beefiected at the'will of'-:the operator as above ex lained.

The ribbon 54 inc udes two strands of different color and is operated inthe well known manner by spool mechanism 55. Between the spools whichare at opposite sides of the mac ine as usual, the ribbon passes throughpivoted ribbon ides 56 which are in the form of levers ivoted. upon ashaft 57, and which, by gravity, hold the ribbon in its normal osition.A link 58 (Figs. 4 and 7) connects one of the ribbon guides 56 with alever 59; The lever .59 is pivotally sup ported upon the depending armof a bell crank lever 60 which is pivoted upon a support 61, and thelower end of which actuated forwardly toward the platen by a scent tothe keys 22 the case of the machine.

spring 62. A link 68 connects the upper end of the lever 59 with an arm64 attached to the rock shaft which is rocked at each depression of atypewriter key, as previously explained. in describing t e typewritingmechanism and the operation of the escapement therefor. Therefore, whenany t pewriter key is depressed to operate one o the type bars 7 theconnections from the shaft 20 raise the ribbon guides 56 a suflicientdistance to present the upper strand of the ribbon over the writing lineto receive the impact of the type. As the train of recording mechanismreturns to. idle position after the typewriting key is released, theribbon guides 56 move downwardly and theconnections from the shaft 20tothe ribbon guides return to idle position. When the parts operate inthis manner all of the records of the t pewriting mechanism will appearin one co or.

The lever 60 is a bell crank lever (Figs. 4 and 6) and has onearmextending rear- Wardly and provided with a lateral extension 65 whichprojects over the adjacent arm which carries the rod 33. When the arms30 are in their idle osition and the recording mechanlsm of t e addingdepartment of the machine is idle, the lever is held stationary and isnot operated when the typewriting mechanism operates. A lever 66 ispivoted at 67 (Fig. 4. and has its lower end in front of the r0 51 andits upper end normally under a projection 68 (Fig. 7) on the lever 60.When an item is recorded by the type-carriers 25 as above explained, thearm 30 moves away from the projection on the lever 60 and permits thespring 62 to retract and actuate forwardly the link 58 and thereby movethe ribbon guides 56 to posit-ion the ribbon adjacent to the writingline. Normally, movement of the ribbon guides is stopped at the time theupper strand of color in the ribbon is positioned at the writing line,by engagement of the projection 68 with the upper end of the lever 66.pivoted to the lever 66 and projects through The link 69 may be employedto move and hold the upper end of the lever 66 out of the path ofmovement of the projection 68, so that movement of the lever 60 will notbe stopped by said lever 66. When the link 69 is'so operated andadjusted to move and hold the lever 66 out of the path of movement ofthe projection 68, the spring 62 moves the ribbon guides 56 to positionthe lowerstrand of color of the ribbon at the writin color of the ri bonis distinguished from the upper strand of color of the ribbon. Whenline, which lower strand ofv A link 69 is the Writin line. \Vhen thelever 66 acts as a stop or the lever 60 the records produced by thetype-carriers 25 will be in the single color of the upper strand of theribbon, but any selected items recorded by the type-carrier 25 may berecorded in the distinguishing color by holding the lever 66 out of thepath of movement of the projection 68, thereby enabling the ribbon ides56 t0 resentthe lower Strand of co or of the rib n to receive the impactof the type in recording operation.

Provision is made in our present invention whereby the totals containedor repre sented in the adding wheels 39 will be printed in a color whichis distinctive from the color of the upper strand of the ribbon. In oneoperation of the machine the typewriting mechanism records in the colorof the upper strand, therefore, the totals will be recorded in a colorwhich is distinctive from the color in which the typewritten records arerecorded, and which may also be distinctive from the color in which theitems are recorded by the type-carriers 25. hen the key 42 is depressedit moves the rod 51 forwardly, as previously explained. As heretoforedescribed, and as illustrated in Fig. 4, the lower end of the lever 66is in front of the rod 51 so that when the rod 51 is moved forwardly itact-uates the lever 66 and moves the upper end of the lever out of thepath of movement of the projection 68. Therefore, when the type-carriersmove forwardly to record the number in the adding mechanism, by the wellknown operation, the lever 60 is actuated by its spring 62 until stoppedby the abutment 70. As previously explained this operation places thelower strand of the color of the ribbon adjacent to the recording lineto receive the impact .of the type, thereby recording the total in acolor which is distinctive from the color in which the type writtenrecords are recorded when the upper strand of the ribbon is utilized forthe typewritten records; and which is also distinctive from the color inwhich the items are recorded when the items are recorded by use of theupper strand of color of the ribbon. A spring 71 (Fi s. 4.- and 7)connects the upper part of the ever (56 with a stationary member andyieldingly holds said lever 66 in position to constitute an abutment forthe projection 68 on the lever 00. Said spring yields to the pressure bythe rod 51 when the key 42 is depressed, and also yields to forceapplied to the element. 69.

\Yhen the adding mechanism is cleared, that is when no number iscontained or represented in the adding wheels 39, it is desirable toindicate upon the paper a clear condition of the adding mechanism whenthe handle or lever 38 is operated. It is desirable to indicate thisclear condition of the adding mechanism before listing the items to beadded. Our invention includes means for automatically indicating a clearcondition of the adding mechanism when the handle 38 is operated withthe key 42 in a depressed position. As previously explained, depressionof the key 42 causes the adding wheels 39 to remain in mesh with theracks 27 during forward movement of the racks, or during forwardmovement of the handle 38. The shaft 40 of the wheels 39 is connected totwo arms 72 which are pivotally held upon a support 73. When theswinging frame 41 is oscillated to raise and lower the adding wheels 39the arms 72 are also oscillated. One of the arms 72 is connected by alink 74 with the,front end of a lever 7 5 pivoted upon a rod or shaft76. The rear or inner end ofthe lever 75 has a pin 77 projectinglaterally over the inner or rear end of the lever 78, so that when theadding wheels 39 are in their elevated position, that is in mesh withthe racks 27, the link 74 and the lever 75 holds the rear end of thelever 78 in a depressed position, and the front end of said lever in anelevated position. A link 78 which connects one of the arms 30 with anarm 79 on the rock shaft 80 is actuated forwardly when the said arms 30are moved forwardly by operation of the lover or handle 38. The bail 81is supported by the rock shaft 80 and is swung downwardly and forwardlythereby when said shaft 80 is rocked by the link 78, in the well Iunderstood manner of the Hopkins patent, No. 1,039,130 and the Dormanapplication No. 339,230. The n ward position of the arm 72 which uphol sthe front end of the lever 7 8, as previously explained, also upholdsthe rear end of a bar 82, so that the downward and forward movement ofsaid bail 81 will engage against the rear end of the bar 82 forwardly.The front end of the bar 82 is pivoted to a latch 83 normally inengagement with the type driving hammer 37 in units order. From theforegoing it is obvious that if the key 42 be held in depressed positionand the handle or lever 38 operated forwardly the bail 81 will releasethe latch 83 from the hammer in units order, permitting said hammer tobe actuated or driven against the type by its spring 84. Sincedepression of the key 42 also causes the lower strand of color of theribbon to be positioned at the printing line when the handle isoperated, and since, in the-clear condition of the adding mechanism, thehammer in units order is released to drive one of the type to print asan indication of a clear condition of the adding mechanism, it is obvious that the character thus printed will be printed in the color ofthe lower strand of the ribbon, which may be differentfrom the color inwhich the items to be added are listed.

typewriting mechanism and said separate From the foregoing descriptionit will be understood that the single polychrome ribbon is acted upon bythe type of both mechanisms, an that the connections for moving theribbon are operated incidentally to the o' ration of the typewritingmechanism an also incidentallyto the operation 7 of the type-carriers25. to utilize one color strand of the ribbon, and that the machinecontains manipulative means whereby selected portions of the records maybe written in distinctive colors.

v to feed paper to both mechanisms, a single polychrome ribbon to beacted on by the type of both mechanisms, ribbon guides ho ding saidribbon, and connections operated incidentally to the operation of saidrecording mechanism to move said ribbon ides to utilize only one colorof said ribn, of means whereby one of said mechanisms may be caused tomove said'ribbon ides to utilize another color'of said ribon,substantially as specified.

2.
